In a high-inflation environment, variable annuities offer a unique blend of investment growth and guaranteed income, making them an attractive option for certain retirees. Unlike fixed annuities, their value rises and falls with market performance, allowing for inflation-beating potential over time. 

They also provide tax-deferred growth and the option to convert savings into a predictable income stream that can last for life. Optional riders can offer added benefits like long-term care coverage or income guarantees, though these come with additional fees. 

However, high costs, market risk, and limited liquidity make them unsuitable for all investors. 

Finsum: For those who’ve maxed out other retirement vehicles and can tolerate some risk, variable annuities may help protect purchasing power while delivering steady income.
